Question

What is the distance between the points (8, -3) and (1,5) ?

Answer 1

Answer:

$d=\sqrt{113}$

Step-by-step explanation:

$(8, -3)= (x_1,y_1)\\(1,5) =(x_2,y_2) \\\\d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d = \sqrt{\left(1-8\right)^2+\left(5-\left(-3\right)\right)^2}\\\\d = \sqrt{(1-8)^2 +(5+3)^2} \\\\d = \sqrt{(-7)^2+(8)^2}\\ \\d = \sqrt{49+64}\\ \\d = \sqrt{113}$
